Title: Improvements in cloth folding machines having automatic edge guide
IPC: B65H45/101
Filed: 1955-04-07
Abstract: 784,878. Folding fabric. LEVER BIAS MACHINE CORPORATION. April 7, 1955 [Nov. 5, 1954], No. 10311/55. Class 42 (2). [Also in Group XXXV] A machine for folding cloth longitudinally comprises a motor operative to move means for guiding the material through the machine, and contact means associated with the guiding means and connected to the motor to be selectively operated by the movement of the edges of the material from a normal path to selectively actuate the motor to restore the movement of the material to the normal path. As shown, fabric A is drawn over a triangular folding table 24 and the doubled fabric passes between a pair of guide rods 26, 27 and around a guide roller 15. Between table 24 and rods 26, 27 the fabric edges are restricted as they pass through channel members 47 carried by a bracket 39 adjustably mounted on rods 26, 27. The fabric edges are normally just clear of the ends of a contact bar 43 centrally pivoted on bracket 39. When an edge of the fabric wanders from its normal path it causes one end of bar 43 to contact one or other of two contact bars 40, 41 so as to energize a reversible electric motor 34 which acts through a linkage 33, 32, 31 to move the lower ends of rods 26, 27 in a direction to restore the fabric edge to its normal path, the upper ends of the rods pivoting at 30. Table 24 and rods 26 are carried by a frame adjustable, by means of a threaded shaft 50 and handle 51, relative to the main frame 10 in accordance with the width of the fabric being folded.

Abstract: 914,820. Photo-electric colorimetry. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R.T. March 25, 1959 [March 26, 1958], No. 10381/59. Class 40 (3). In an arrangement for measuring the chromaticity of a light source, e.g. a fluorescent lamp 21 (Fig. 9), light from the latter which passes through a slit 22 is collimated by lens 23 and then passes through an interchangeable template 24 and a (metal) interference filter 25 and is then imaged on a photo-electric device 27 by means of lens 26. The interference filter (Fig. 1) which produces monochromatic has a spectral transmission ## as shown in Fig. 2. In the present invention the chromaticity co-ordinates are computed from the response of the photo-electric device which, in the case of the #X# co-ordinate is equal to #S##X#d# where S# is the spectral distribution of the light source. The co-ordinate X#, which over the range considered, varies as shown in Fig. 4, and which may be computed from the tristimulus co-ordinate X = #<SP>780</SP> 880  S##X#d# is utilized in conjunction with the spectral response of the photo-electric device ## (Fig. 3) to produce an apertured template as shown in Fig. 5, or, preferably as in Fig. 6, representative of a function different templates being produced for the co-ordinates #y# and #z#. These templates are then successively positioned at 24 (Fig. 9) and the chromaticity computed from the response of the photo-electric device by using the relationship given above. If desired, three separate interference filters and a template having three apertures corresponding to the different coordinates may be selectively exposed in the same optical path between the lenses 23, 26 (Fig. 10, not shown). By arranging the template 24 (Fig. 9) to produce a sensitivity corresponding to the function #y# and employing a diaphragm (Fig. 11, not shown) having eight adjustments, each corresponding to the transmission of light in beam wavelength bands, the arrangement of the invention may be employed to measure colour rendition.

Title: Edm parameter control system
IPC: B23H1/02
Filed: 1973-03-06
Abstract: 1384863 Electro-erosion INOUE-JAPAX RESEARCH Inc 6 March 1973 [7 March 1972] 10683/73 Heading B3V [Also in Division G3] An electro-discharge machining process is controlled by monitoring gap conditions for certain time intervals and correspondingly varying stepwise a process parameter in an appropriate sense according to sensing signals stored in a memory. In the system described, a first counter responds to normal machining pulses and is automatically reset to zero when a count of, say, eight is reached. A second counter responsive to abnormal pulses caused by short-circuits or arcing is simultaneously reset unless it reaches a count of, say, four before the first counter reaches eight. In this situation, an "abnormal" signal is produced and triggers a monostable multivibrator. A third counter responds to intermittent retraction or reciprocation of the tool electrode which is intended to allow the working gap to be cleared by liquid dielectric. This counter may also have a limit of eight, whereupon it resets to zero and produces a "normal" output signal. However, if the second counter reaches its limit first, the third counter is immediately cleared so that the occurrence of the "normal" signal is delayed. The signals produced are fed through logic circuitry, Fig. 1 (not shown), and control a bidirectional counter which determines the values of chosen process parameters. Rapid changes in parameter values leading to hunting are prevented by a second bidirectional counter with along time constant acting as a regulator for the first bidirectional counter. The output of the latter counter is connected through a decoder D4 to ten setting circuits each as shown in Fig. 2. Each circuit includes transistor switches Tr1, Tr2 coupled to monostable multivibrators Ml, M2. When triggered, multivibrator M1 provides at terminal UP a pulse of duration which determines the distance of electrode retraction during reciprocation. Multivibrator M2 is triggered by a circuit COT in response to sensed gap voltage at terminal G and provides a pulse at terminal UP, the duration of which determines the time interval between reciprocation cycles. Alternatively the setting circuits may vary the time between machining pulses, the electrode feed rate, or the supply of dielectric liquid. In an example, a cylindrical copper electrode is used with a paraffin dielectric.

Convention date, July 27, 1929. [Class 142 (i).] With hooks controlled through relay arrangements from a paper pattern.-In a double lift dobby having its hooks 3 controlled at will either through a relay by a paper pattern band on a cylinder 21 or directly by a wooden lag chain on a cylinder 39, the hook levers 1 are mounted loosely on a shaft 2 carrying loosely two levers 5 connected by a shaft 6 and moved up and down by cams 10 on a shaft 11. A hand crank having two cams 17, 18 on its hub is movable into two positions, in one of which it is clutched to the shaft 11 and in the other is loose thereon. Reading needles 22 carried by wires 23 secured to bell-crank levers 25, 26 loosely mounted on a spindle 24 are periodically raised by a rod 29 carried by arms 28 fixed to the spindle 24, which is rocked by a lever 30 and the cam 18. The needles 22 are then allowed to fall and the bell-crank levers 25, 26 of those needles which enter perforations in the endless paper band on the cylinder 21 rock to such an extent as to move under the corresponding levers 1 corresponding hooked arms 7, 8, which hang from the shaft 6. When the arms 7, 8 are raised by the pivot 6, selected levers 1 are thus rocked. Every two picks the cylinder 21 is moved by means of the cam 17 engaging a ratchet wheel 19, a spring-controlled lever furnished with a roller preventing undesired rotation of the ratchet wheel. The cam 17 is of such a width that it engages the wheel 19 in both positions of the hand crank on the shaft 11, so that the hand crank can be unclutched from the shaft 11 and used to rotate the cylinder 21 backwards with the loom stationary. The spindle 6 may be raised and fixed in a position wherein the arms 7 are out of engagement with the levers 1, and the pattern cylinder 39 may be used to control the levers. In a modification, the reading needles are curved and are fixed direct to the bell-crank levers. In another modification the hand crank is provided on an additional shaft driven from the loom and driving the shaft 11 through spur wheels, one of which is loosely mounted on the additional shaft but may be coupled thereto by the hand crank or be driven by this hand crank.

Title: Improvements in or relating to linear-dimension gauges
Inventor: HAIDEGGER HANS
IPC: G01B3/18
Filed: 1950-05-04
Abstract: 686,411. Linear-dimension gauges. EBAUCHES SOC. ANON. May 4,1950 [May 4, 1949], No. 11097/50. Class 106 (ii). A linear-dimension gauge comprises a graticule mounted in a feeler and a second graticule secured in the body of the gauge, the graticules being so marked and arranged that when the feeler is displaced by a work-piece the marks indicate whether the work-piece is within predetermined tolerance limits. In one embodiment, the invention is applied to the internal gauge described in Specification 646,992. The movable feeler 5, Fig. 2, is held in known manner in the innermost position to which it is pushed during a gauging operation against a spring, by a wedge brake. A transparent scale 8 carried by the feeler moves adjacent to a fixed transparent graticule 11 bearing a vernier scale 12, Fig. 3. After the gauging operation, the scale may be read through a magnifying lens 13 arranged in a transverse hole in the gauging head. The graticule 11 also bears a line 16a and lines 17-19 which co-operate with elongated graduations of the scale. The lines 17-19 are marked according to the tolerances allowed for certain standard fits. If for a particular fit the corresponding line, say 17, is to the left of the adjacent elongated scale marking and the line 16a is to the right of the elongated scale marking adjacent thereto, then the dimension gauged is within the limits of tolerance. Additional lines similar to the lines 17-19 may be provided for other standard fits and some of these may be arranged in a lower row, the elongated scale markings being correspondingly lengthened. For external measurements, the normally fixed gauging anvil of a micrometer may be formed in a similar fashion to the feeler 5 shown. In this case, the spindle of the micrometer is set to the nominal size of the work-piece and the fixed graticule 11, Fig. 5, bears for each range of dimensions, e.g. for the range 0-3 mm., a series of short, parallel lines 27 arranged in pairs, each pair corresponding to the tolerance range for a given standard fit. The moving graticule carries a single line 28 for each range. If this line falls between the appropriate lines 27, the dimension gauged is within the chosen tolerance limits. A feeler 5 associated with graticules, similar to the graticules 8, 11 shown in Fig. 5, but for one range only, may form one calliper of a non- adjustable gauge constructed for a given nominal size of work-piece.
